Lux is simply this.

Lux: The International System unit of illumination: 1 lumen uniformly distributed over an area of one meter.

It's Lumen's you should be looking at, the higher the better, anything over 5000 should do you for a start, my two bulbs churn out a total of almost 24,000, but cost a lot, these are not tubes or Halogen, but have the ballast built into them, they look like a compact flo. light bulb, a pic. Cheers.
